Terminology

Docker Deamon: the process taking place in the host remote operating system. It is responsible for building, running and distributing the containers.

Docker Client: the command line tool (or app with GUI) which allows th euser to interact with the Deamon.

Containers: the isolated environments in which the application can run, containing all the necessary dependencies.

Images: the blueprints of the application which form the basis of containers. The are divided into Base Images and Child Images.

Dockerfile: a text file whichis used to construct the images (this is the file which we actually write in, together with the code of the application).

Files in the main directory

• test.py : containes the actualy python code which is run in the container.
• Dockerfile: the file used to build the image.

Files in GWs

• Dockerfile: the image installs GWpy, Jupyter and Pandas, whiah are all needed to run the jupyter notebook
• WaveFormEncoder.ipynb: jupyter notebook with the Pix2Pix neural net
• GW_test.py: a few lines of code which use GWpy libraries as a proof of concept

How to create and run the app

• Run the command sudo docker build -t test . to build the image
• Run the command sudo docker run test to run the app
